The bridge at this interchange involved a severe skew angle which was a significant challenge. The roundabouts for this project had to be designed to accommodate an extremely long oversize truck used to transport bridge beams that are manufactured nearby. The maintenance-of-traffic design for this project was complex due to MDOT’s stringent requirements for I-94 lanes to remain open as well as significant vertical grade differentials between closely spaced work zones and temporary travel lanes. The DLZ team included several key subconsultants, so team coordination added a layer of complexity to the project as well.

The project was in compliance with AASHTO and MDOT standards, specifications, and provisions.
